Hate using the "beta" and "alpha" verbiage of yore, but it pretty effectively communicates that what we're seeing here is the old tileset for 1000 A.D. There's also a different Zenan Bridge look going on as well. Will get these in the encyclopedia in the next update. If anyone knows OKD, we would murder to get better scans of those pages.

What catches more my attention is that lower-right picture in the first image. Seems like a blend of 1000AD and 2300AD interiors. Considering it shows Lucca fixing/maintaining Robo as Crono, Marle, and Frog watch, it makes me curious about the context. Early version of Lucca's house?

I could definiitely call it an early work, the two top pictures make the world travel look squarish, i know you can only move in 4 directions but it doesnt feel that way, its open, while the square paths look older, more ff1 era.

If it was the future, then I wonder about Frog's prescence there. Perhaps he would join earlier. Maybe it's part of a cutscene somewhen else. I don't think the text next to the picture gives context. From what little I can understand, it seems to talk about "party of 3 members", and lists a few of the characters. I see the words Girlfriend (or just Girl Friend? Hard to tell), Frog, and Robot there, alongside Crono's name.

It's not placeholder. The top name is Tatakau, which means more or less "Battle" of "Fight". It's the standard Attack command. The bottom name is Item, also self-explanatoru. Now, for the middle names, the box of the left has Renkei, which means like "Cooperation" or "Link". While the other two are "Waza", which is "Skill" or "Ability". Respectively, they're the Combo and Tech commands. So no, it all points that was finished.

In fact, form the context of the text in the first image, it sounds like it's explaining the Renkei commands. As in, the Double/Tripple techs. Perhaps the only thing we can question is why only one of the Tech's turns into Combo if, well, Double/Tripple Techs would imply at least one other character would have Renkei, not Waza.

We've seen a variation on that early Zenan Bridge screenshot before, in low quality, in one of the Next Gate images.(https://www.chronocompendium.com/images/wiki/thumb/c/c3/V_Jump_1996-02_Page_197.jpg/335px-V_Jump_1996-02_Page_197.jpg)(see image page here (https://www.chronocompendium.com/Term/File:V_Jump_1996-02_Page_197.jpg.html) for more detail.)

The dome screenshot is the same one in the Brazilian magazine scan.

The other battle screenshots appear to be of the sample battles shown in the 1994 preview video

You mean like that Sonic 2 beta cartridge that was stolen and years later someone decoded and unlocked some of the unfinished levels? I thought thats how we found the singing mountain stuff used in CE...

I look at the bottom right picture with the mountains in the background, was this an early theory of using like mode 7 to walk around the world? a precursor to a 3d world view from the 1st person sort of?
